I've recently begun working on a new server build for my company which will be running very heavy CPU (and RAM) workloads. I have put together a spreadsheet of the core parts I'm looking at using, and am wanting some suggestions on parts that may do the job better or cheaper. Although I want to keep the price down, if you think I have skimped out on anything, please do let me know. The spreadsheet only includes the main components, but if you have any suggestions for things like network cards, I'm open to that as well.
The sheet
Note, I am located in Austrlia, so all prices are in Australian Dollars.
